This invention relates t'o an improved magazine tack hammer, and-has especial reference'to the type lof hammers, which' embodies in its construction a magazine re-y l 6j, looking'i'n thev directionf'of the arrow?

whereby the centrifugal force" produced by swinging the hammer and 4the force of theA hammer blows may be' utilized' to"l 'shak'ethe' tacksV out of the magaz'ineV into` the delivery channel; and the provision of a novel device' for retaining a tack in setting position' on" the lian'imerhead, which willI permit a quick' j releaseof the tack from the hammer by a .been properly or nailed,` and drivenhome.v y ,v 'l

, the illustrated embodiment of theiny vention, the hammer head 1, which'mav be of any desired rform or shape, consists of thetwo sections or plates 2 -and'3, suitably riveted together and forming ahollo'w head, as shown. The plates 2 andVm'ayconve1'1ientlybe. forn-'ielf-fot drop' orgings.

The'Av lower portions 13 of the flanges merge into the enlargements 8 at the lower end of the` hammer head and the inner faces 111' of the flanges vat this point connect with curved inner lateral'flanges 15 cut from the inner longitudinal faces of the enlargements 8.

l Said angesl Vextend clear tothe front face of, thehammer, as shown m14`1g. 2.

When `the two halves of the hammer head are securedtogether, the inner edges of the lshank of a tack, and thestriking faces 9 of the enlargements 8 yare similarly spaced flanges 10, throughout their, entire extent, are spaced apart 'sufciently togreceive the apart. There is thus formed a channel .15a having a slotlG wide enough to permit pas-- vsage of the Shanks of the tacks T vwhich project rearwardly beyond the flanges,` as shown, but not wide enough to allow the heads of the tacks to pass through, the heads being retained by the flanges. `It will be seen :that the heads of the tacks passing i T is positioned just in front of the lower por-l down the Achannel 15el are retainedfirst by the upper, middle and lower portions Vof the .flanges 10, and krnext by engagement with the.A lateral fianges 15` of the enlargements 8.v v After being set'by a blow lo f the hammer they head of a` tack retained betweenv said enlargements may pass outY the front of the hammer, in themanner which will hereinafter appear.v l l*The depth of the channel 15a is determined by a metal plate 17 located within the hollow7 hammer head and secured totheL half-sec tions 2 and 3 thereof, by means of rivets.

VSaid plate 17 is provided withank upper section 18 located directly behind the upper portion 11 of the flanges 10 andconnected by a rearwardly projecting flange 19 withl an inclined section 20 which is located iny front.v of the inclined portion `12 of the flanges 10. The inclined section 20 of the plate merges into the lower section 21,vvhich f tion 13' of said flanges10,the lower end 22 of4 l 'the flanges 10 than they intermediate in- .55

said plate terminating some distance above j v the flanges of the enlargements 8 to permit free passage of -the tacks. Upper section 18 of plate 17 is spaced a greater distance from clinedsection20 and lower section 21, thereby providing .a-channel for the passage of the tacks which is deeper at the top than at Vthe bottom. The outer edge ofthe flange 19 is preferably beveled or curved, as shown at A 19a to permit freepassage of the heads ofr the tacks, into the lower shallow portion ofl Y the channel which begins at theflange 19.

y'The `upper end 23 of plate 17 terminates some distance beneath the shoulders atthe rupper ends`offthewhalvesj2l` and 3 ofvgthe ling a tackin setting position onthe head, until they tack i'sreleased infthej manner .which will` appear hereinafterj. Y The' tack magazine2l is closed by a swinging'plate or ycover 27 pivoted at v28 ftofthe head and adaptedfwhen invclo'sed position torestfon the front edges 29 of Vthe hollow'head. Preferably, the free endl of coverj27 is bent, as shown,` and saidl bent end vis adapted to enter a groove' 30 formed in the'top 'fjaceof the head to retain thecover 27 in closed position. Mounted in a socket adjacentthe top faceof thehead is a vpin 31V having a head 32 'on the rear end of its shank. The

shank of the pin projects -through'the socket `in thehea'd andthe forward end of said shank is adaptedV toengage thecover 27. By pressing on the head 32 ofthe pin the `bent end of the cover may be sprung out of the groove 30, thereby releasing the cover and permitting it tojswing into open posi-` tion. In this way, access may be' had to the -magazine when it isv desired to replenish the supply ofltacks.V

Pivotally mounted at 33 vwithin the lower chamber26 is a'ta'ck-retaining member or stop 34 having itslower face 35 curved to conform withthe curvature'of the flanges 15 ofthe enlargements S'. Said curved face 35 in effect forms al continuation 'of vthe 'n channel wall formed by the plate 17 andthe outer edge of said curvedv face isnorm'ally pressed toward or zinto engagement with the flanges 15' to prevent exit of'a tack out of the front face of the head, until leffected by a rearward slidingmovement or pull of 'the hammerhead. The front face ofv the stop 34 normally Vlies'flushiwith the front edges of the head and beneath said. front face the stop 34 is' cut away, as shown at 36,

to receive the free end vof ya leaf spring 37. Thisspring 37 passes beneaththe pivot 28 -of cover 27, and'r the free end of the spring presses outwardly against kthe shoulder 36 of the stop to retain the'latter normally in position to bar the exit ofa tack;v

The invention provides r'a novel cut-off operable to permit one tack at a time to pass from the lower portion 'of the channel 15 around Ainto/a dependent positionfrom the striking face of the head, While the next succeeding tack and allA theother tacksin the channel arepositively held against passage into such dependent position, until another operation of the cut-olf is ef fected.
